Replaces #3359

This allows successful build and use of file deletion, a.k.a. move to trash

Tested with a source build of simp with the trash feature enabled.
Without this commit, simp fails to build on NetBSD when the trash feature is enabled.

Also, I've added the new symbols to semver and made sure these functions are available on a minimal NetBSD environment.

This allows successful build and use of file deletion, a.k.a. _move to trash_

Tested with a source build of `simp` with the **trash** feature enabled.

Thank you so much!

You're welcome. On my TODO list, learn how to squash non-consecutive commits (if it's even possible?).

Thanks

@JohnTitor Hmm ... this failure seems unrelated.

This failure was already present yesterday on merged #3284

Nah, it's different. The cause is that rustc removed an apple target and the fix is here: #3362
I'll retry once the above is merged :)

EDIT: Why?!? Merge order, should I sync my branch? I still believe this is unrelated to my PR.

@JohnTitor I had a closer look at this locally but, I'm getting only a warning not an error using Rust-1.72

@JohnTitor So no, I can not call bors myself.

EDIT: At this point, it should actually be: Add backtrace definitions and support for getmntinfo and getvfsstat but, also at this point, I don't want to mess around anymore.

Please give bors another go 🙏

I see I need one last correction. Closing this once more and will open a new one.
Might take a day or two, want to run tests on it.

Auto merge of #3368 - 0323pin:main, r=JohnTitor

backtrace definitions and support for getmntinfo and getvfsstat

After the failures of merging #3361 as a follow-up to #3359 I've spent sometime making sure everything is indeed supported and defined.

```
~> grep -r "MNT_WAIT" /usr/include/sys/fstypes.h; grep -r "MNT_NOWAIT" /usr/include/sys/fstypes.h; grep -r "MNT_LAZY" /usr/include/sys/fstypes.h
#define	MNT_WAIT	1	/* synchronously wait for I/O to complete */
#define	MNT_NOWAIT	2	/* start all I/O, but do not wait for it */
#define	MNT_LAZY 	3	/* push data not written by filesystem syncer */
```

```
~> grep -r "getmntinfo" /usr/include/sys/; grep -r "getvfsstat" /usr/include/sys/
/usr/include/sys/statvfs.h:int	getmntinfo(struct statvfs **, int)
/usr/include/sys/statvfs.h:    __RENAME(__getmntinfo90);
/usr/include/sys/fstypes.h: * waitfor flags to vfs_sync() and getvfsstat()
/usr/include/sys/statvfs.h:int	getvfsstat(struct statvfs *, size_t, int)
/usr/include/sys/statvfs.h:    __RENAME(__getvfsstat90);
/usr/include/sys/syscall.h:/* syscall: "compat_90_getvfsstat" ret: "int" args: "struct statvfs90 *" "size_t" "int" */
/usr/include/sys/syscall.h:#define	SYS_compat_90_getvfsstat	356
/usr/include/sys/syscall.h:/* syscall: "__getvfsstat90" ret: "int" args: "struct statvfs *" "size_t" "int" */
/usr/include/sys/syscall.h:#define	SYS___getvfsstat90	483
/usr/include/sys/syscallargs.h:struct compat_90_sys_getvfsstat_args {
/usr/include/sys/syscallargs.h:check_syscall_args(compat_90_sys_getvfsstat)
/usr/include/sys/syscallargs.h:struct sys___getvfsstat90_args {
/usr/include/sys/syscallargs.h:check_syscall_args(sys___getvfsstat90)
/usr/include/sys/syscallargs.h:int	compat_90_sys_getvfsstat(struct lwp *, const struct compat_90_sys_getvfsstat_args *, register_t *);
/usr/include/sys/syscallargs.h:int	sys___getvfsstat90(struct lwp *, const struct sys___getvfsstat90_args *, register_t *);
```

Also, I've made sure the code compiles with rustc 1.72.0 without warning or errors.

```
~> cargo build --release
    Updating crates.io index
   Compiling libc v0.2.148 (/home/pin/Git/libc)
    Finished release [optimized] target(s) in 8.87s
```

Moreover, the _move to trash_ functionality has again been verified using [simp](https://github.com/Kl4rry/simp) compiled with this commit as patch, in combination with the patch submited to [trash-rs](Byron/trash-rs#84).
